To all whom it may concern.-

' Be it known that I, EDWARD JOSEPH Enrcs SON, a citizen of the UnitedStates, and a resident of San Francisco, in the county of San Franciscoand State of California, have invented a new and-Im roved Automatic FeedDevice, of which the fbllowing is a full, clear, and exact description.

The invention relates to water distribution; and its object is toprovide a new and improved automatic feed device for supplying water toflush-tanks, leader-traps, surface drains, and similar contrivances, andthe water-supply of which is not sufiiciently regular to maintain apermanent seal, as required by modern sanitary plumbing.

The invention consists of novel features arts and combinations of thesame, whic will be more fully described hereinafter I and pointed out inthe claims.

A practical embodiment of the invention is represented in theaccompanying drawings,

forming a part of this specification, in which similar characters ofreference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of the improvement. Fig. 2 is asectional plan view of the same on the line 2 2 of Fig. 1. 3 is asectional side elevation of a modified form of the improvement. Fig. 4is a side elevation of my improvement applied to a trap.

As is well known, water-outlets from a dwelling, factory, quired to betrapped and the seal of the trap to be permanent. Traps on ordinaryplumbing fixtures used every day are readily supplied with the necessaryamount of water tomaintain the seal of the trap; but with traps such asare used on leader-pipes, surface Both methods mentioned areobjectionable,

as in the one case it requires the occasional opening of'a faucet, andif this is not done at regular intervals the permanent seal is notmaintained. The second method is objectionable for the reason that thetrap in time becomes choked with foul matter and becomes a gas-produceritself instead of a barrier for above ObJGGlJlOIlS are or like building.are re-v foul air passing into the house. With my lmprovement,presently to be described, the entirely removed, and

water is frequently fed to the trap, so asto maintaln a permanent Asillustrated in seal thereof. Figs. 1 and 2, a casing A,

preferably in the form of a cylinder, is con .nected atits lower end bya pipe B with the water-pressure supply for the house, and the upper endof the said cylinder is connected by a pipe C with a faucet or otherfixture C in the house, so that when the faucet is opened a reduction ofpressure takes place in the upper end of the casing A.

Within the casing A is mounted to slide a loosely-fitting piston D, thment of which is limited by a stop E, held on e upward movea screw-rodE, screwmg in a plug A, em

ployed for closing the upper end of the casing The lower end of videdwith a valve F, normally seated on the valve-seat G, held on a plug G,screwing in the lower end of the casing A, the opening G of the saidvalve-seat connecting with the pipe G leading to the trap or otherdevice G to be supplied with water for maintaining -a permanent seal.Fig.

The operation is as follows: Normally the piston D is in a lowermostposition in the vertically-disposed casing A, as the pressure of thewater is practically equal on both sides of the piston, as the inlet andoutlet of the cylinder is connectedwith a water-supplyof the. samepressure.

When the faucet or like fixture with which the pipe 0 is connected isopened, then a reduction of pressure takes lace in the upper end of thecasing A, and

ence the preponderance of pressure against the under side of the pistonD causes the latter to slide upward until stopped by the upper end ofthe piston abutting against the stop E. The piston in its upwardmovement carries the valve F along, so that the latter uncovers thevalve-seat G, and hence the Water passing into the lower end ofthe thepiston D is procasing A by the supply-pipe B flows through theopening Gto the trap to supply the latter with suflicient water to maintain aermanent seal. It is understood that as ong as the faucet is open thepiston D is' held in an uppermost position but as soon as the faucet isclosed the piston D immediately drops back by its own weight into itslowermost position, so that the valve F. is again seated on thevalve-seat G and communication between the supply-pipe B and the trap iscut off. It

is understood that the piston D fits sufficiently loose in the casing Ato equalize the water-pressure on both ends of the piston for the latterto return to its seat by its own weight as soon as the faucet connectedwith the pipe C is closed. r.

If desired, a valve may be controlled by the piston D for supplyingwater to the trap or other contrivance, and in this case the stem H ofthe valve is extended up through. the valve-seat opening Gr to connectwith the piston D, as shown in Fig. 3, so that when the piston is forcedto slide upward on the reduction of pressure in the upper end of thecasing I 5 A then the valve is actuated by the piston D for the purposementioned.

The device is very simple and durable in construction, is not liable toget easily out of order, and is arranged to maintain a perma- 2 nentseal by frequently supplying water to a trap or other contrivance.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. An automatic governing device comprising a casinghaving an inlet connected with a fluid-pressure supply, an outletconnectedwith a faucet, and a controlled outlet, a piston in the saidcasing, and means whereby the said piston may control the controlledoutlet.

2. An automatic governing device comprising a'cylinder having an inletconnected with a water-pressure supply, and an outlet 3 5 connected witha fixture such as a faucet, a

piston slidable in the said cylinder intermediate the said inlet and thesaid outlet, and means controlled by the said piston for feeding waterto the device to be controlled.

3. An automatic governing device con1 4o prising a cylinder having aninlet connected with a water-pressure supply, and an outlet connectedwith a fixture such as a faucet, a piston slidable in the said cylinderintermedimeans controlled by the said piston for feeding water from thesaid inlet by way of the said cylinder to the device to be controlled.

4. An automatic governing device comprising a cylinder having an inletconnected with a water-pressure supply, and an outlet connected with afixture such as a faucet, a piston slidable in the said cylinderintermediate the said inlet and the said outlet, a valve moving with thesaid piston, and a valve-seat normally closed by the said valve andleading to the device to be controlled.

5. An automatic governing device comprising a cylinder having an inletconnected with a water-pressure supply, and an outlet connected with afixture such as a faucet, a piston slidable in the said cylinderintermediate the said inlet and the said outlet, a valve moving with thesaid piston, and a valve-seat normally closed by the said valve andleading to the device to be controlled, the said valve-seat beingadjacent to the said inlet to allow water to flow from the inlet by wayof the cylinder through the said seat at the time the piston is raised.

In testimony whereof I have signed my name to this specification inthepresencc of two subscribing witnesses.
